Benzoic acid is occasionally used as a raw material supplement in food products and is sometimes generated during the fermentation process. In this study, the production of naturally occurring yogurt preservatives was investigated for various starter cultures and incubation temperatures, and considered food regulations. Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus delbru...

The intestinal microbiome might be an important contributor to the development of type 2 diabetes. This study was designed to test the hypothesis that oral administration of Bifidobacterium species (spp.) (including B. longum, B. bifidum, B. infantis, and B. animalis) may both ameliorate insulin resistance and reduce the expressions of inflammatory adipocytokines. Male Swiss-Webster mice fed a ...

We investigated the effects of O2 on Bifidobacterium species using liquid shaking cultures under various O2 concentrations. Although most of the Bifidobacterium species we selected showed O2 sensitivity, two species, B. boum and B. thermophilum, demonstrated microaerophilic profiles. The growth of B. bifidum and B. longum was inhibited under high-O2 conditions accompanied by the accumulation of...

Bifidobacteria are colonizers of the human gut, where they are interacting with their host as well as with other members of the intestinal microbiota. Teichoic acids (TAs) have previously been shown to play an important role in modulating microbe-host interactions in the human gut. However, so far, there is a paucity of information regarding the presence of TAs in the cell envelope of bifidobac...

Aflatoxins are highly toxic, mutagenic, teratogenic and carcinogenic compounds produced by some species of Aspergillus, especially A. flavus and A. parasiticus. This study was conducted investigate the effect of some strains of probiotic bacteria against toxicity induced by contaminated diet with aflatoxins in male rats. Animals were divided into 6 equal groups each group contains 7 rats. The f...

Introduction: The antimicrobial compounds have attracted attention these days all around the world. Applying essential oils (EOs) as the herbal antimicrobial materials and natural antioxidant are so valuable in the food industry. In this study the effects of Rosmarinus officinalis essential oil (REO) with different phenol contents was investigated on the properties of ...

In recent years, the probiotic bacteria, as the food additives, have been introduced into numerous foods, of which the dairy products especially yoghurt has played an important role in carrying these bacteria (such as B. bifidum and L. acidophilus). The purpose of this study, determine the effects of different ziziphora Clinopodioides (50, 100 and 150 micrograms), in two passages after and befo...

Objective(s): The preclinical reports have shown that specific probiotics like Bifidobacterium bifidum (B. bifidum) and Lactobacillus acidophilus (L. acidophilus) can be applied as the biotherapeutic agents in the inhibition or therapy of colorectal cancer via the modification of gut bacteria. In the previous studies, we have assessed the impact of L. acidophilus and B...

Background: Well-controlled clinical studies in the developed world have shown that probiotics can shorten the duration of acute non-bacterial diarrhea. We aimed to evaluate the efficacy of a probiotic consisting of a mixture of Lactobacillus acidophilus and Bifidobacterium bifidum in the treatment of young children with acute diarrhea in Mashad, Iran Methods: Sixty-two hospital inpatients aged...
